Replacing lysine with aspartic acid is really a change in the primary structure (the sequence of the amino acids - think in a chain). But because they are really different amino acids, the effect is much more profound and will affect the tertiary structure of the protein.
Lysine has a basic, positively charged side chain. Aspartic acid has a negatively charged carboxyl group for its side chain. So, they are two very different amino acids.
Since the tertiary structure of a protein is a result of the interactions of the various interactions of the amino acid side chains, you have to think about what a swap of a basic positive amino acid with a negatively charged amino acid could cause.
For example, if the lysine side chain interacted in ionic interactions (i.e. attraction to a negatively charged amino acid), if you swap it for aspartic acid which is negatively charged it will now repel the other amino acid's side chain and that would disrupt the tertiary structure of the protein. It would also likely cause disruption to the quaternary structure as well.
If this change was in an important part of the protein (e.g. the active site of an enzyme) then it would likely disrupt the proper functioning of this protein.
If you wanted to make the least amount of change to a protein by making a mutation to that lysine amino acid, you would choose other basic amino acids which are histidine and arginine.
Not TOO sure here, buuuut I’m pretty sure it’s TRUE because a state is much more complex then a whole country, and therefore has a lot more constitutions.
An asexual reproduction might be considered the production of new individual by mitotic divisions. there are many forms for this type of reproduction process such as fission which occurs to lower plants and animals like a bacteria. Then , we have budding (fungi and multi-cellular animals), spare formation (bacteria and fungi) , etc
The right option is; c. Both A (judgment) and B (inhibitions)
The first area of the brain affected by alcohol is the area that controls judgment and inhibitions. The first area of the brain to be affected by alcohol is the cerebral cortex, followed by hippocampus, cerebellum, frontal lobe, medulla and the reticular activating system. The cerebral cortex is responsible for intellectual functions of the brain such as judgment, thinking, inhibitions, reasoning, organizing, voluntary movement, and total behavior.
